I have seen quite a few bikes now with the fork installed the wrong way around, so far this is the only suspension fork I have seen done like this though. Post pictures/links to whatever bike butchery you have seen, anything is welcome.

Apparently a relatively popular corporate event is to do "bike builds" as a sort of team building exercise. At one such event, I was hired to do "safety checks" on the bikes and assist the teams if they had any questions while building them according to the instructions in the boxes. They had about 20 teams going and I was walking around giving advice whenever I saw something egregiously wrong. Of the 20 bikes, I would say that on about 8 of them, I had to advise them to turn the fork around. After they were all built, they came over to my stand and I basically had to rebuild most of them to make them not be deathtraps. Fortunately, the teams all moved on to some corporate ra-ra motivational thing while I worked before the presentation ceremony where the kids at a local charity came to receive their new bikes. I shudder to think about how many of those kids wouldn't be alive today if left to the devices of the most confident (and usually the most inept) member and therefore leader of the bike building teams. LOL

That probably explains why there was always at least one really grumpy mechanic in every shop I worked in.

This part of your comment particularly rings true for me.

Sometimes, backward forks are purposefully installed.

For this bike, reasons are to minimize flop, as flop fights against the stabilizing force of trail

Steering Geometry of Short Wheelbase Recumbent Bikes

I’ve been riding and studying recumbents in all their forms intently for about 12 years now, and ideas have been slowly forming in my head regarding what they should and should not be, mostly…

rothrockcyrcle.wordpress.com

For a given wheel and tire size, there are only two independent variables among the four remaining variables (the four we’ve been talking about – head tube angle, rake, trail, and flop). The head tube and and the rake themselves aren’t of any particular importance, in a sense. They, in and of themselves, don’t dictate how the bike will handle. What actually matters are the trail and flop figures.

head tube angle to 85 degree, and with the negative 40 mm rake fork got me the trail figure I wanted, which was about 70 mm, and a very low flop of 6 mm. This is a whopping trail-to-flop ratio of 11.66.
